Police Chief Ken Johnson said the Fairview Police Department and the East Multnomah County Major Crimes Team are still investigating the death of the girl, identified as 10-year-old Miranda Crockett.

Police said Crockett died at the King's Garden Apartments on NE 207th. She was taken from the apartment complex by ambulance on Saturday.

Police have not said how she died.

On Monday, Johnson said officers arrested Chandra Ilene Rose, 34, in connection to the case. She faces two counts of criminal mistreatment and reckless endangerment, police said.

Rose appeared in court Tuesday afternoon, where the judge increased her bail from $12,000 to $100,000. The judge also sealed court documents that outline why Rose was arrested in connection with Crockett's death.

Rose is the girlfriend of Crockett's father and has three children of her own. The children were placed in protective custody.

Neighbors who spoke with KATU News Tuesday said Crockett's father was heartbroken about his daughter's death.

"He came walking by and he was carrying, like, a little stuffed animal and a few things in his hands. He just looked out of it," said Mark Seibel, who works with Crockett's father. "And I said 'what's up? What's going on?' And he says 'Miranda passed away,' and I just said 'oh my God' and put my arms around him."

Police said Crockett's father was not at home Saturday when his daughter died.

"She was a beautiful little girl," said neighbor Angela Anderson. "She was so friendly. She's going to be missed."
